Shipborne impact type bump-driven wave generatorTechnical Field
The invention belongs to the field of new energy equipment, and particularly relates to a shipborne impact type bump-driven wave generator.
Background
Small vessels such as small yachts, fishing boats, traffic boats, etc. require power even when moored to provide lighting, communications, and some electricity for life and low power production, and currently use battery packs to store electricity from the main power devices of the vessels as a power supply. While conventional floatation devices such as marine towers, beacon lights, fish ponds, and cage blowers also require electricity, it is often inconvenient to configure the fuel powered device to generate electricity to address the power supply problem due to limited volume, cost and efficiency of use, and maintenance issues, typically powered by batteries and replaced periodically.
In order to reduce the power consumption and save the energy, the wind power or solar batteries are adopted as an anchor standby power supply or a constant power supply for ships and floating devices, but the mode has the defects of complex energy conversion mechanism, large volume and weight, small power generation density corresponding to unit volume, high installation and maintenance cost, high installation position, poor wind resistance and the like, so that the popularization is difficult. In practice, the waves which are surging in the rivers, lakes and seas contain huge energy and are far higher than the energy density of wind power and sunlight, and some beach power stations use sea wave power generation, but the mechanism is relatively complex, the volume and weight are difficult to be miniaturized, the design working condition is harsh, the cost is high, and therefore, the beach power station is difficult to transplant and apply to small ships and standing floating devices.
Therefore, there is a need to develop a small wave power generation device that uses the high density energy, high electrical energy conversion efficiency and power density, small volume and size, reliable operation, low cost, and convenient maintenance contained in waves as an anchoring backup power source for small vessels or a daily operation power source for floating devices.

In this embodiment, the voltage output coil of the generator stator 704 is connected to an on-board electrical load through a rectifying circuit and a rechargeable battery.
In the present embodiment, the generator stator 704 is mainly configured as an induction coil, and the generator rotor 705 includes an inner magnetic pole and an outer ring, which mainly serve as a weight ring for increasing rotational inertia.

The working procedure of this embodiment is as follows:
A typical application of this embodiment is shown in fig. 4, for example, where it is only necessary to install the embodiment in a power silo at the bottom of the hull of a small-sized ship and connect its power output end to an electric load. In the process of anchoring or sailing of the ship, the ship body can bump up and down along with the fluctuation of waves, so that the base 1 of the invention also bumps up and down along with the ship body, and the whole inertial mass formed by the sliding sleeve 3, the cross arm 5 and the tip cone 6 tends to keep the original position due to inertia. When the ship moves upwards along with the waves, the inertial mass body slides downwards along the slide bar 2 to reduce the distance between the inertial mass body and the base 1, so that the tip cone 6 at the lower side of the cross arm 6 acts on the impact generator 7 at the lower side, the tip cone 6 drives the internal thread hollow sleeve 709 to move downwards through the rubber cap 712 (at the moment, the return spring 710 is compressed) and drives the main shaft 703 to rotate forwards through the coupling of the transmission thread between the internal thread hollow sleeve and the outer edge of the head of the main shaft 703, and then the generator rotor 705 is driven to rotate forwards through the one-way bearing 706 (at the moment, the one-way bearing is in a locking state) and part of mechanical energy is temporarily stored in the form of rotational inertial energy. When the hollow sleeve 709 is pressed to the lowest position, the coupling transmission between the hollow sleeve 709 and the outer edge of the head of the main shaft 703 is stopped, the main shaft 703 stops rotating, the generator rotor 705 continues to rotate forward due to inertia without being restrained by the unidirectional bearing 706 (at the moment, the hollow sleeve is in an unlocking state), the stator coil of the generator is coupled with a magnetic field generated by the magnetic poles of the rotor to generate a pulse induction potential, and finally, the mechanical energy contained in the bump of the ship caused by waves is converted into electric energy with stable voltage by utilizing a rectifying circuit and an energy storage battery of the rectifying power storage module, and the electric load equipment on the ship is powered.
When the ship moves downwards along with waves, the whole inertial mass slides downwards along the sliding rod 2 to increase the distance between the whole inertial mass and the base 1, the rubber cap 712 and the return spring 710 start to return, the extension of the return spring 710 drives the internally threaded hollow sleeve 709 to move upwards, in the process, the coupling of the transmission threads between the whole inertial mass and the outer edge of the head of the main shaft 703 drives the main shaft 703 to rotate reversely to enable the one-way bearing 706 to be in an unlocking state, so that the forward rotation of the generator rotor 705 still kept due to inertia at the moment is not hindered, and the rotational inertial energy stored by the generator rotor 705 is still converted into electric energy to continuously supply power for the ship-mounted electric load equipment.
In the above-described one-cycle pitching movement up and down, the interaction of the tip cone 6 on the upper side of the cross arm 6 with the impact generator 7 on the upper side and the electromechanical movement process take place synchronously, but in antiphase over time.
Therefore, the above process is repeatedly and alternately performed between the inertial mass and the upper and lower impact generators 7 along with the up and down pitching of the ship, so that the present invention can convert the mechanical energy contained in the pitching of the ship caused by the waves into electrical energy and continuously supply power to the on-board electrical load device during the mooring or sailing of the ship.

Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
